in the given figure AB || CD PROVE THAT p+q+r = 180
As per the figure, the angle equation p + q + r = 180 is proved.
In geometry, an angle is defined as the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. When two lines are parallel, the angles opposite to each other are called corresponding angles.
In the given figure AB || CD, we are asked to prove that the sum of angles p, q, and r is equal to 180 degrees. This can be proven using the concept of corresponding angles.
Since lines AB and CD are parallel, the angles opposite to each other are equal, i.e., p = r. Therefore, the sum of angles p and r can be represented as 2p.
Furthermore, since lines AB and CD are parallel, the alternate interior angles are equal. This means that angle q is equal to angle p.
Therefore, the sum of all three angles, p, q, and r, can be represented as 2p + q.
And since we know that p = q, we can simplify this to 3p.
Finally, since the sum of angles in a triangle is always 180 degrees, we know that
=> 3p = 180 degrees.
Solving for p, we find that p = 60 degrees.
Therefore, the sum of angles p, q, and r is equal to
=> 2p + q = 2 * 60 + 60 = 180 degrees,
which proves the statement p + q + r = 180 degrees.

An urn contains 8 green and 6 pink balls. Six balls are randomly drawn from the urn in succession, with replacement. That is, after each draw, the selected ball is returned to the urn. What is the probability that all 6 balls drawn from the urn are green? Round your answer to three decimal places.
The probability of drawing a green ball in one draw is 8/14 = 4/7. Since the balls are replaced after each draw, each draw is independent of the others. Therefore, the probability of getting 6 green balls in a row is (4/7)^6 ≈ 0.066.
Rounding to three decimal places, the probability is approximately 0.066.
The distance (in miles) that a person can see to the horizon can be approximated by
d(n) = V1.49n, where n is the elevation (in feet above sea level) of the person.
Approximate the elevation of a person who can see 85 miles to the horizon.
Step-by-step explanation:
the function is
d(n) = sqrt(1.49×n)
so,
85 = sqrt(1.49×n)
85² = 1.49×n
n = 85²/1.49 = 7225/1.49 = 4,848.993289... ft

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.
The equation for this problem is this:
[tex]\frac{5}{3} + \frac{2}{9}[/tex] (> < =) [tex]1\frac{9}{8}[/tex]First, we need to find a common denominator between [tex]\frac{5}{3}[/tex] and [tex]\frac{2}{9}[/tex].
What is a common denominator?A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.
To find the common denominator, we can multiply the denominators, 3 and 9.
3 × 9 = 27Now we know that the two new fractions are going to have a denominator of 27.
[tex]\frac{?}{27} \frac{?}{27}[/tex]Now, we can use these equations to solve for the numerator.
9 × 5 = 453 × 2 = 6Now, the fractions look like this:
[tex]\frac{45}{27} \frac{6}{27}[/tex]To add them together, we can use this equation:
[tex]\frac{45}{27}+ \frac{6}{27} = \frac{51}{27}[/tex]Now, we need to convert [tex]1 \frac{9}{8}[/tex] into an improper fraction.
What is an improper fraction?An improper fraction is a fraction that has a numerator that is greater than the denominator. For example, [tex]\frac{3}{2}[/tex] is a improper fraction.
[tex]1\frac{9}{8}[/tex] = [tex]\frac{17}{8}[/tex]To convert [tex]\frac{51}{27}[/tex] and [tex]\frac{17}{8}[/tex] into common denominators, we need to multiply the denominators, like we did above.
8 × 27 = 216The new fractions will look like this:
[tex]\frac{?}{216} \frac{?}{216}[/tex]To solve for the numerators, we can use these equations:
17 × 27 = 4598 × 51 = 408The fractions now look like this:
[tex]\frac{408}{216} \frac{459}{216}[/tex]Now, convert them to mixed numbers.
[tex]\frac{408}{216} = \frac{17}{9}[/tex][tex]\frac{459}{216} = \frac{17}{8}[/tex]Therefore, 5 thirds + 2 ninths < 1 9/8.

If Mark reads 18 pages less than originally planned, he will need 5 more days to complete the book. If he reads 24 pages less than originally planned, he will need 8 more days to finish. How many pages are in the book?
Answer: Let's denote the original number of pages Mark planned to read as "P".
From the first statement, we know that P - 18 pages will take 5 more days, which means P pages will take 5 days less, or 5 - 5 = 0 days.
From the second statement, we know that P - 24 pages will take 8 more days, which means P pages will take 8 days less, or 8 - 8 = 0 days.
So, we have two equations:
P - 18 = 5 * X
P - 24 = 8 * Y
Where X and Y are the number of pages Mark reads per day.
Since X and Y are equal, we can substitute one of them for the other:
P - 18 = 5 * (P - 24) / 8
Expanding the right side and solving for P, we find that P = 288 pages.

It took 2 electricians 5 days to wire a house. How long would it take 10 electricians?
Answer:
1 day
Step-by-step explanation:
Assuming all the electricians work at the same rate, we can use the formula:
(time x workers) = constant
So, if 2 electricians took 5 days, we have:
(5 x 2) = (time x 10)
Simplifying, we get:
10 = time x 10
Dividing both sides by 10, we get:
time = 1
Therefore, it would take 10 electricians 1 day to wire the house.

Answer:
Step-by-step explanation:
The formula for kinetic energy is:
KE = (1/2) * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
We are given the mass of the pick-up truck as 1500 kg and its velocity as 31.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:
KE = (1/2) * m * v^2
= (1/2) * 1500 kg * (31.0 m/sec)^2
= (1/2) * 1500 kg * 961.0 m^2/sec^2

Help apex!
D. $128.94. is the total amount of money Nate will earn after taxes when he buys a CD for $1000 The formula for compound interest is:
A = P * (1 + r/n)^(nt), where A is the amount after t years, P is the principal amount, r is the interest rate as a decimal, n is the number of times interest is compounded per year, and t is the number of years.
We can use this formula to calculate the amount of money Nate will have after 5 years:
A = 1000 * (1 + 0.03/4)^(4 * 5) = 1000 * (1 + 0.0075)^20 = 1000 * 1.1629 = 1162.9
The interest earned is 1162.9 - 1000 = $162.9.
And the amount of interest taxed is 20% of $162.9, which is 20% * $162.9 = $32.58.
So, the total amount of interest earned after taxes is $162.9 - $32.58 = $130.32.

Steve is driving at 35 mi/h when he makes an emergency stop. His brakes lock and his tires leave four skid marks of equal length. The drag factor for the road surface was 0.97 and his brakes were operating at 90% efficiency. How long might the skid marks be to the nearest foot?
The skid marks would be approximately 1.9 ft in length to the nearest foot.
The drag factor of the road is given as 0.97 and the braking efficiency as 90%. To calculate the skid marks, we need to use the coefficient of friction (μ) between the tires and the road surface. The formula for calculating this is: μ = (2 x Drag Factor x Efficiency) / 100.
Therefore, μ = (2 x 0.97 x 0.9) / 100 = 0.0174
Once we have the coefficient of friction, we can use the following equation to calculate the skid marks: Skid Length = Initial Speed x Reaction Time x 0.5 x μ.
Since the speed is given as 35 mi/h and the reaction time is assumed to be 0.75 seconds, the skid marks will be: Skid Length = 35 mi/h x 0.75 s x 0.5 x 0.0174 = 1.9 ft
Therefore, the skid marks would be approximately 1.9 ft in length to the nearest foot.

The number of hospitals in a certain country has been declining for many years. In 2014, there were 5,727 hospitals, but, in 2017, there were only 5,571. Assuming this trend is linear, write an equation for the number of hospitals H in the this country t years since 2000
Step 1: Calculate the initial number of hospitals. In 2000, there were 5,727 hospitals, so the initial number of hospitals (H0) is 5,727.
Step 2: Calculate the rate of change. From 2014 to 2017, the number of hospitals decreased by 156. Therefore, the rate of change (r) is -156.
Step 3: Calculate the equation. The equation for the number of hospitals H in this country t years since 2000 is H = H0 + rt. Substituting in the values from Steps 1 and 2, this gives us H = 5,727 – 156t.
Therefore, the equation for the number of hospitals H in this country t years since 2000 is H = 5,727 – 156t.
First order equations include linear equations. In the coordinate system, the linear equations are defined for lines. A linear equation in one variable is one in which there is a homogeneous variable of degree 1 (i.e., only one variable). More than one variable may be present in a linear equation.
